All official jRate releases are source releases. We may in the future
provide binary packages (.rpm, .deb) to make
evaluation of jRate easier, but we don't yet. Generally if you're building
for a specific environment (especially if you're building for a real-time
environment or if you're building a crossed toolchain for embedded
development), you'll want to pass build-time configuration parameters to
jRate anyway.

Development snapshots are occasionally made available. These releases are
less polished and stable than official releases, but include recent fixes
and feature enhancements in advance of the next stable release. You might
want to browse the snapshots area for the latest.

Subversion access is also available to obtain cutting-edge
features and bugfixes. However, jRate is under active
development and the development version in the repository
may not compile or work properly. Still, you may find jRate's
Subversion repository an invaluable resource if you're interested in our
development work, trying to determine if a bug has already been addressed
for the next release, or want a preview of coming features. See the
SourceForge jRate
project Subversion page for details on accessing the repository.

RTJPerf is a collection of tests meant to measure the performance of
any RTSJ-compliant Real-Time Java VM.

Currently RTJPerf provides mostly time-efficiency tests based on a
synthetic workload. The tests present in the current version of
RTJPerf are described in the document "Evaluating Real-Time Java
Features and Performance for Real-Time Embedded Systems" which can be
found here.
